CoinSpy: Get alerts on bitcoin transactions for any address

[vtrac]

With the holidays, I had some free time to hack and made a new site:

http://coinspy.io

You can "follow" any number of addresses. The system watches network and as soon as a transaction gets broadcast, you'll get an email with the details.  The emails come pretty fast, normally within a few seconds. You can follow "famous" addresses like the silk road address and find out if and when the FBI will do anything with the BTC. Or you can just follow the public addresses of your cold/offline storage and get alerted in case the private keys are compromised or somehow used (this is why I created it for myself).

Anyway, I would love to hear feedback and get some ideas as to how to improve CoinSpy.

Idea seems good, but to me, is an awfully easy way to associate addresses with their owners, and many people won't be able to use this as they have the practice of only using each address once.
And it also seems like the About and Contact links fail to work?
Tested with one of my addresses, let's see how it goes.

good service, much like the service of blockchain.info's watch only / api recall.

it would be good to also have an option that it sends an API call to a website on notification. then some users wont have to be so reliant on blockchain.info.

then people can have a backup service to blockchain.info, and if proven stable and effective, it would become more popular.

csv doesnt work for me, it adds "u'"

Error validating Bitcoin address. Probably not valid: [u'1XXX', u'

I think you probably had a space between the addresses, which wasn't handled properly. Should be fixed now. Mind trying again?
